To (til who/it it nmty coil/writ:

He it known that l, Vio'ron E. l lnwn'nps, a citizen of the United States, residing at l l orcester, in the county of l'lorcester and Uommon wealth o f ll lassachusetts, have in vent ed a new and useful llnnn-ovemeut in Conwayore for Metal Bars, of which the following is a specification, accompanied by drawil'igs forming a part of the same, in which to Figure l represents a plan view of a convcyer for metal bars embodying my invention. .l ig. 2 is side view slniwing the position of the conveyer to receive a metal bar. Fig. 3 is a side view showing the position of the conveyor when rocked to raise a metal bar. Fig. 4; is a detaclled view of one of the rocking notched conveyor-bars. l ig. 5 is a transvm'se sectional view of one of the notched conveyor-bars on line 5 5, Fig. 1. liig. 6 is a sectional view of one of the bearings ol the notched con veye rbars, showing the adjusti ngscrew for adjusting the position of the bar. Fig. 7 is a sectional view of a conveyor-bar, showing a modified form.

5 Similar reference-ligures refer to similar parts in the dilferent views.

My present invention relates to a conveyor :for conveying metal bars preferably from a lower to a higher plane; and it consists in the 3 constrluiztion and arrangemeiiit of parts, as hereii'ialter described, and pointed out in the annexed claims.

Referring to the accompanying drawings, 1 '1 denote a pair of com'eyer-ro]ls carried on shafts 2 2 and driven by miter-gears 3 from a common driving-sln1ft l Journaled in bearings 6 in vertical planes parallel with the axes of the shafts 2 are the inclined rocking bars 7. Each of the rocking 4 bars 7 is provided with radial notched blades ti and fl, arranged at right angles to each other. The blade 8 is provided with notches to form triangular teeth ll), and the blade 9 is similarly notched to form triangular teeth ii. The bars 7 are held in their bearings 5 and t' in an inclined position, as represented in Flgs. 2 and 3, and the trlangnlar teeth 10 are provided with inclined sides '12, the mclinatiou of which is greater than the coellicient of friction, so that a metal bar supported 5 on the triangular teeth ll) near their apex will slide by gravity to the bottom of the notch, in the position represented by the bars '1?) [3, Fig. 2,. f limilarly the triangular teeth 11 are provided with inclined sides H, on which a metal bar when supported near the top of the teeth, as represented at If) 15 Fig. i), will be caused to slide by gravity to the bottom of the notches. llhenever a bar has been caused to slide by gravity from the top to the bottom of one of the ta-iangular teeth, it will be brought into contact with surfaces It; at right angles to the inclined surfaces l2 and I L of the trial'ignlar teeth. lhe lowermost triangular teeth 11 of each of the rock- 5 ing bars Treceives the bar in a horizontal position and is provided with guides 17 17 to conduct the bar by a longitiulimil movement in the direction of the arrow '18, Fig. 1, across the com eyer, the longitudinal IIIOVOlTlQlil] of 7 the bar being facilitated by the rotating rolls 1 l. Each of the rocking conveyor-lmrs 7 is provided with an arm 19, and these arms are pivotally cm'mected by links 2U 20, and the lirst rocking conve,verlJar 7 in the series is also provided with a radial arm 21, which is cormected by links 522 22 with a pistonrod 25" which is reciprocatial by a hydraulic cylinder 24-, lniving the usual valve connections (not shown) to enable the movement of the $0 rocking bars to be controlled by the operator. \lhen a metal bar has been entered across the conveyer-bars in the guides lei, power is applied to the hydrauliij: cylinder to rock the convever-l ars 7 one-quarmturn, which will 5 raise the teeth '1 'l from a horimntal to a vertical plane, which will lift the bar oil the rolls 1 and out of the guides 17 and cause it to be supported upon the inclined surfaces let of the teeth ll. and near the apex of the teeth. ll/l'ien the bar has been brought into this position, it will slide by gravity down the inclined sides 14 until it strikes the surfaces 1h. The apices of the trial'igular teeth 10 are arrangedin planes midway between theapices 05 of the triangular teeth ll, so that when the oar has slid to the bottom of the lirst set of teeth ii at the lower end ot the conveyor-bars T and the conveye '-bars I are rocked in the opposite direction one-quarter turn, thereby bringing the triangular teeth 10 from a horizontal to a vertical plane, the metal bar is lilted by and supported upon theiuclined sides 12 ol the teeth 10, upon which the bar slides into the position shown by the bar 13 in Figs. 1 and E2. The rocking motion of theconveyerbars 7 is then continued, causing the metal bar to be alternately supported first by one set ol teeth 10 and then by the other set of teeth 11 with a period between each alternate i5 rocking of the conveyorbars to allow the metal bar to slide down the inclined sides ol? the triangular teeth, and this operation is repeated until the metal bar has been moved along the eonveyer-bars T by a stepdrv-step movement, each successive step causing the metal bar to be raised to a higher level due to the inclination of the conveyor-bars 7. \Vhen the metal bar has thus been traversed with a ste -hy-step movement the entire length of the conveyor-bars 7, it will be linally delive red upon a pair of conveyer-rolls 25 25, carried upon shafts 2G 26, and driven by mitergears 27 from a common driving-sha Ft 28, allowing the metal bar to be removed by a longitudinal movement ol the conveyor, the ditlerence in the level between the conveyorroils l and the conveyor-Hills 25 corresponding to the elevation of the metal bar by the successive lifting movement of the conveyorbars 7. Each 01 the conveyor-bars 7 is longitudinally adjustable in its hearings 5 and 3 by means of an adjusting-screw 29, hearing against the lower end of the conveyor-bar, th: 'eby enabling the conveyor-bars to be accurately adjusted, so as to bring the liftingteeth of one bar in alinement with the corresponding lifting-teeth of the remaining bars, so that the inclined sides 12 and l lof each set of teeth 10 and 11 will lie in the same plane wh n ln'ought into action to support a metal bar, and the surfaces 16, which serve as stops to limit the movemeirt of the bar, when :ICtlr y gravity will also lie in the same plane, so that when the bar has slid by gravity down iliued sides cl the triangular teeth and 'iln'iiiihly against the step-sur- "np an'ting-surtaces ot the metal .alinement will serve to straighten.

l ngitudinal adjustment by the adjnstirig-screws the vertical adjustment 5 by n"- ansot a removo E d i raise or a thickness, as may be rehearing.

1 only, the ei'nployment cf conrtwer bars having projecting such conveyor was shown in Letwhich can be exchanged ters Patent ot' the United States No. 701,024, is ued to me May 27', 1902. lo the above patent, however, the projecting arms of the inclined skids served only as stops to check the downward movement of a metal baralong the skids, while in my present invention the inclined sides of the teeth form ways along which the metal bar is moved by gravity, and the inclined sides of one row or set of teeth is made to overlap the inclined sides of the adjacent row or set of teeth.

Although I have shown my invention in Figs. 1 to 3 ol the accompanying drawings as en'ibodied in a conveyor in which the rocking conveyor-bars are inclined and adapted to raise a metal bar trom a lower to a higher plane, l do not conline myself, however, to the use of inclined bars. it is obvious that the movement ol the metal bar in a line parallel with the axes ot the rocking conveyer-bars would be accomplished it the COHVQYOY-bftlfi were to be journaled in hearings in a horizontal plane or it the delivery end of the bars were lower than the receiving end.

l n the conveyor illustrated in the accompanying drawings the di llerent series ol teeth 10 and 11' are alternately brought into position to support the metal by a rocking motion im parted to the cmiveyer-bars 7; but by arranging the teeth as shown in Fig. 7, with the series 01 teeth 10 and ii alternating around the conveyor-bar 7, it will be obvious that a rotary motion could be imparted to the con veyer-bar 7 by any known means with the same result viz., that of bringing the diti'crent series of teeth 10 and 11 into action alternately.

llhat l claim as my invention, and desire to secure by Letters Patent, is

1. in a conveyor for metal bars, the combination of a series of conveyerbars, teeth projecting from said bars and having inclined sides and arranged in alternating rows or series, with the inclined sides of the teeth in one series overlapping the inclined sides of the teeth in the next adjacent series, and means for brie g the diilerent series successively into supporting relation to a metal bar held th :reon.
